To lithium-ion batteries, which are now used in mobile gadgets,many questions. Their term of office is not particularly high, it is less than dictate the needs of users and the market. Researchers at Stanford University have created a technology that will increase the capacity of the batteries and increase their effectiveness. The result of their work was the next-generation lithium battery. She – by modern standards – a real long-liver.
As you know, in most modern mobile devices used lithium-ion batteries. They include three major components: electrolyte, anode and cathode. As the anodic material is normally used graphite as a cathode – Li-ferro phosphate. During charging, lithium ions migrate from the cathode to the anode, which retains the stored energy. In operation, the power supply ions drift in the opposite direction. U.S. researchers offer substitute the anode material on lithium metal, which will greatly increase the capacity of the battery, and hence the battery life of devices on one charge.
Experts from Stanford University propose to use the anode special protective layer consisting of relating to each other tiny carbon domes. This structure scientists call nanospheres: thickness of the protective layer is only 20 nanometers. Coating of nanospheres has chemical stability and good elasticity, allowing significantly improve performance batteries. However, the timing of the practical implementation of the proposed method is not reported.
While no real devices based on new items from Stanford not, but work on converting promising batteries in a mass product is already underway. Experts believe that the discovery will help portable electronics to operate more than 24 hours without recharging (even under the most extreme scenarios).
